Structural and Catalytic Alterations of Dehydrogenases After Photooxidation^*

Lactate Dehydrogenases: Structure and Function

“…3. The presence of histidine in the active center of other LDHs was suggested by Millar and Schwert (84), and Robinson et al (85), from studies on the effects of photooxidation. DiSabato (86) and Holbrook et al (87) found evidence that a tyrosine may be at the active site.…”

The Role of the Sulfhydryl Groups of Lactic Dehydrogenases*

“…Levine (1962) and Gerstein et al (in preparation) have presented evidence indicating that alterations in protein structure may result in changes in immunologic properties. Moreover, certain amino acid reagents have been found to promote modifications of the structure of lactic dehydrogenases as detected by changes in immunologic properties (Kaplan and White, 1962;Robinson et al, 1963). However, as indicated in Table IV, there is no shift in the complement-fixation characteristics of the p-mercuribenzoate-bound CHLDH when compared to the native dehydrogenase.…”

Photocatalytic degradation of crystal violet over semiconductor zinc oxide powder suspended in aqueous solution

“…Contamination of aquatic environment by these dyes is a serious problem as dyeing, printing and textile industries release their coloured effluent in nearby rivers, lakes, ponds, etc. However researches are now directed towards assessing the extent of dye pollutiont 8 Crystal violet is used as a dye for wood, silk, paper and in inks. It is also used as a biological stain.…”
